APPARATUS FOR TRANSPORTING GASES.

Application filed March 11, 1922.

To all whom it may concern:

Be it known that I, PIERRE E. HAYNES, a citizen of theUnited States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Apparatus for Transport ing Gases, of which the following isa specification.

This invention relates to portable glass apparatus adapted for the transportation of ases from place to place, the apparatus of t e invention being especially adapted for use in connection with gases, for example neon, which because of their scarcity and consequent high price, require the exercise of extraordinary precautions to prevent loss and contamination.

The invention includes a novel type of valve which is to a high degree proof against breakage and accidental displacement, and includes also an improved form of terminal connection whereby the apparatus may be quickly and securely attached to the gas-producing or gas-using apparatus. A specific embodiment of the invention will be described in connection with the annexed drawing, in which the figure shows an elevation partly in longitudinal section of an apparatus in accor ance with my invention.

1n the drawing, 1 represents the gas container proper. To the container is integrally attached the neck 2, which serves as a filling and discharging conduit for the container. Integrally attached to the con duit 2 at the end remote from the container 1 is an accurately ground valve seat 3 which lies within the conduit and the axis of which coincides with that of the conduit. Cooperating with the valve seat 3 is a con ical valve head 4 ground to an accurate fit with valve seat 3. An orifice 5 in the seat and an orifice 6 in the head are so located that in one position of the parts these orifices are brought into register, thereby forming a gas conduit connecting the interior and exterior of the container. The valve head 4 carries an integral enlarged portion 7 accurately ground to a regular surface 8.

That portion of the apparatus which has thus far been described is portable and de signed to be shipped back and forth between the place where the gas is produced and the place where it is used. Either the gas-pro Serial No. 543,060.

ducing or the gas-using apparatus, preferably both, are provided, with a conduit 9 having an integral enlarged portion 10 which has the accurately ground regular surface 11 conforming exactly to the ground surface 8 of the part 7. Because of the facility with which a plane surface can be formed or reproduced, the surfaces 8 and 11 are preferably plane surfaces, though surfaces of other forms, for example conical, spherical or cylindrical, might be used, the only essential requirement being that the surfaces on the parts to be fitted together shall be in contact at all points to prevent gas leakage. Part 7 has in its ground surface an orifice 12 while the part 10 has a corresponding orifice 13, these orifices being so placed that they coincide when the ground surfaces are brought together. With the valve in open position, there is then a free gas passage connecting the interior of the container 1 to the gas-producing or the gas using apparatul.

The conduit 2 carries adjacent the valve seatprojecting hooks l-l, and similar projecting hooks 15 are provided on the valve head 4. Rubber-bands 16, suitably arranged on these cooperating hooks, serve to prevent any undesired relative movement, either rotary or longitudinal, between the valve surfaces and insure that the valve will not become accidentally opened or displaced in. such manner as to permit leakage. The parts 7 and 10 are likewise provided with projecting hooks 17 and 1.8 and rubberbands or the like 19 secured to these hooks, which serve a similar purpose and prevent leakage at the juncture of the ground surfaces 8 and 11.

The method of using the apparatus is as follows: Upon return of the apparatus to the gasproducing station, the valve composed'of narts 34 will be closed, the container 1 will contain some residual rare as at a pressure considerably below atmospheric, and the valve head 4 will be filled with air at atmospheric pressure. The apparatus is placed with its ground surface 8 against the ground surface 11 of the gasproducing apparatus, and the rubber-bands 19 are applied to hold these parts securely in contact. The air is then evacuated from the valve head 4, the valve remaining closed. The valve is turned to open position bandsdfi. 'If there 1s any reason to -.s uspect;. that the residual gas in the container is containinated, or it, the container is to be re- 5 neeting' the apparatus fromthe i ga5+produc ing apparaitus; the "valve igiithenhturn ed to its'cbesed nosi'tion andisecured in this position byuhe bands ltl.
